Ann works as a consultant in Washington, DC. She has preferences over goods x,y and z represented by the following utility function:

U(x,y,z)=1/3ln(x) + 1/3ln(y) + 1/3ln(z)

Suppose that she's endowed with e_x, e_y, e_z amount of these goods, and she faces prices p_x, p_y, p_z . Suppose that Ann's current wage is w^DC and that her labor supply is inelastic and equal to 1, l=1 (we assume she doesn't value leisure at all).

From now on, assume Ann's DC endowments are e_x=e_y=e_z=100 and that her current wage is w^DC=60. Calculate Ann's utility from working in DC, u⁰
